FIELD OF THE DISCLOSURE

The present disclosure generally relates to off-planet manufacturing and more particularly to apparatus, systems and methods for utilizing in-situ materials as feedstock for additive manufacturing devices.

BACKGROUND

The statements in this section merely provide information related to the present disclosure and may not constitute prior art.

Sourcing building materials is essential for off-planet operations, yet transportation of building materials from Earth to an off planet location is prohibitively expensive, complicated, and time consuming.

Hauling each piece of equipment necessary for a mission from Earth to an off-planet location such as the Moon, Mars, an asteroid, or other celestial body is problematic because the launch vehicles utilized to deliver payloads to space (e.g., the Atlas V® vehicle (available from United Launch Alliance, LLC of Centennial, Colo.), the Falcon 9 v. 1.1 vehicle (available from Space Exploration Technologies, Inc. of Hawthorne, Calif.), and the like) have limited payload capacities, cost over $1,000 per kilogram to launch a payload, and have significant wait times and approval processes associated with launching a payload. Despite the difficulty of transporting materials off-planet, since the first missions into space and to other worlds, everything has been brought from Earth. The in-situ, on location materials have been studied but never utilized.

Utilization of in-situ resources found in space or on celestial bodies would enable exploration, study and exploitation of such environments in ways which parallel expeditions in the Age of Exploration. During the Age of Exploration, naval vessels explored the oceans in search of new trade routes and lands. During these expeditions, explorers “lived off the land,” catching fish, trapping game, and harvesting timber. Without taking advantage of local resources, such expeditions would have had to have been significantly larger and likely would not have traveled as far because transporting enough food, spare parts, fuel for fires and other materials would have occupied significantly more cargo volume. Samples of newly discovered flora and fauna were also gathered for study and exploitation upon their return. These explorers also sought and found rare minerals such as gold, which they shipped back to Europe for significant profit.

Upon reaching a newly discovered land, explorers often constructed small settlements from locally-sourced materials in order to more efficiently gather local resources. These settlements were also used to resupply other expeditions. Some also served as construction facilities (e.g., a shipyard), constructing ships, wagons, and other vehicles for use in transporting goods back to Europe or to other locations and for further exploration. Utilization of locally-sourced materials enabled self-sustaining settlements and colonies and enabled longer, multi-stop exploration or trading expeditions.

Given the foregoing, apparatus, systems and methods are needed which facilitate in-situ resource utilization in space and on other celestial bodies. Additionally, apparatus, systems and methods are needed which facilitate reducing mass and volume devoted to on-site habitats and equipment.

Additionally, what is needed are apparatus, systems and methods which facilitate sample and material return from off-planet sites such as the Moon, Mars, asteroids, and other celestial bodies.

SUMMARY

This Summary is provided to introduce a selection of concepts. These concepts are further described below in the Detailed Description section. This Summary is not intended to identify key features or essential features of this disclosure's subject matter, nor is this Summary intended as an aid in determining the scope of the disclosed subject matter.

The harvesting and use of materials (e.g., lunar regolith, Martian soil, extraterrestrial minerals, ores, ice, dirt, or dust, or the like) from sources in space is very useful because it will reduce mass and enable new paradigms for space missions. In order for the resources to be used, they must be conditioned in such a way to enable manufacturing methods and devices to utilize them. The conditioned material can be used for multiple applications. Applications include common uses similar to terrestrial utilizations as well as more space-specific applications such as being used for heat shielding, sample return mechanisms and containers, radiation shielding, and structures. The devices and processes described enable the use of locally-sourced materials for not only the described manufactured components but for use in any desired manufacturing process. Another capability the present disclosure enables is for the combination of multiple elements into one device that allows material to be collected and processed into a usable form. This type of device, for many applications, does not exist in even an Earth environment.

Aspects of the present disclosure meet the above-identified needs by providing apparatus, systems, and methods which facilitate construction of parts, habitats, and other structures using in-situ materials. Aspects of the present disclosure are adapted to use locally sourced regolith, minerals, ore, or other solid materials to produce objects. Objects produced may be small objects, such as a hand tool, sample return container, or the like. Larger objects may also be produced, such as a shelter, a habitat, a launch or landing pad, roads, or portions thereof.

Such apparatus, systems, and methods enable more capable missions because less up-mass launched from earth, a celestial body starting point, a staging point, or the like must be devoted to structures and parts which can be created on site. The use of in-situ materials may facilitate more efficient, cheaper, and more advanced types of exploration and settlement missions in space. There are currently many examples of what the materials could hypothetically be used for but little effort has been placed into the gathering and processes of the materials. Aspects of the present disclosure enable such hypothetical uses. There currently is no infrastructure in space to enable the use of materials and the amount of materials that are brought from Earth are limited by launch and cost restrictions. The present disclosure enables the building blocks for in space infrastructure and enables new types of missions to be created.

Aspects of the present disclosure provide a process for returning samples or other materials (e.g., rare earth minerals, desirable elements or compounds, objects constructed off-planet) to Earth or to another location.

In an aspect, the creation of containers, structures, and shielding using in-situ material is disclosed. Such structures do not need to be launched from Earth, rather they may be constructed on-site. One example is the creation of sample containers using local resources to house samples that are returned to Earth. Such a container may be created on the Moon or Mars, then filled with Lunar or Martian material and placed on a return vehicle is a direct example. In other aspects, locally-sourced materials may be used to construct entire return vehicles and also filling them with local resources.

In an aspect, a process for creating feedstock suitable for utilization by an additive manufacturing device is disclosure wherein the feedstock is created from in-situ materials. Raw, in-situ material is gathered. Such material may be, for example, lunar regolith. The collected material is then processed in order to identify and/or create material suitable for use by the additive manufacturing device. All manufacturing processes require the base material (i.e., the feedstock) be prepared to certain shapes and sizes to be handled by machinery or humans in order to create the necessary end product. Most traditional manufacturing requires the workable material be larger than the final product that is to be machined. On the other hand, many additive manufacturing process require the feedstock to be small relative to the end product being produced, thereby requiring processing and sorting of the collected material. The processed material may be placed in a conditioning device, which will physically and/or chemically process the locally-sourced material into a usable form. Feedstock (e.g., a concrete-like composite, a powder of metal alloy, or a spool of polymer) may be created from the conditioned material. The feedstock may be used to produce desired end products.

The present disclosure may be utilized to create, augment and/or repair heat shields (e.g., ablative heat shields) in order to facilitate the return of a spacecraft that has landed on a celestial body. Heat shields are one of the major mass considerations of the subsystems that are necessary to protect a spacecraft from disintegrating during entry into planetary atmospheres. While many focus on reducing the mass of the heat shield through the use of more durable materials or integration of complex subsystems, almost all designs require the device to be built and flown from Earth. Thus, a high mass penalty at launch will almost always be incurred by propelling the heat shield of the containment return vehicle with the spacecraft into space. Such heat shields, or a significant portion thereof, are often not utilized until the spacecraft returns to Earth, therefore spacecraft may be launched to an in-situ resources location (e.g., the Moon), carry out a mission, construct a heat shield from in-situ resources using apparatus, systems, and methods and return to Earth or another location, protected by the heat shield made from in-situ materials. In this manner, the present disclosure facilitates launching more useful up-mass because less up-mass must be devoted to the return heat shield. Furthermore, additive manufacturing devices utilized to produce the heat shield from in-situ materials may be utilized to create other useful objects. Depending on operational considerations, the additive manufacturing device may or may not be returned on the return portion of the flight.

Further features and advantages of the present disclosure, as well as the structure and operation of various aspects of the present disclosure, are described in detail below with reference to the accompanying drawings.

DETAILED DESCRIPTION

The present disclosure is directed to apparatus, systems and methods which facilitate construction of parts, habitats, and other structures using in-situ materials. Aspects of the present disclosure are adapted to use locally sourced regolith, minerals, ore, or other solid materials to produce objects. Objects produced may be small objects, such as a hand tool, sample return container, or the like. Larger objects may also be produced, such as a shelter, a habitat, a launch or landing pad, roads, or portions thereof.

Aspects of the present disclosure provide a process for returning samples or other materials (e.g., rare earth minerals, desirable elements or compounds, objects constructed off-planet) to Earth or to another location. In an aspect, a sample return vehicle comprising a sample return container is created. The sample return container is manufactured from conditioned in-situ materials by an additive manufacturing device. The sample being returned is placed within the container by the additive manufacturing device or by another device or an astronaut. Portions of the sample return vehicle (e.g., the body, the motor nozzle) may be manufactured from conditioned in-situ materials by the additive manufacturing device, thereby printing all or multiple portions of a sample return vehicle. The sample return vehicle may then be launched on a trajectory which returns the sample to Earth or another desired destination.

Apparatus, systems and methods described herein may utilize apparatus, systems, and methods described in co-pending applications, namely, U.S. patent application Ser. No. 14/331,729, filed Jul. 15, 2014 and entitled “Manufacturing in Microgravity and Varying External Force Environments”; U.S. patent application Ser. No. 14/555,234, filed Nov. 26, 2014 and entitled “Metal Casting Methods In Microgravity And Other Environments”; and U.S. patent application Ser. No. 14/604,743, filed Jan. 25, 2015 and entitled “Recycling Materials In Varying And Reduced Gravity Environments,” all of which are incorporated by reference herein.

An exemplary utilization of apparatus systems and methods described herein is a sample return mission from the Moon, Mars or another celestial body. A spacecraft is launched from, for example Earth, on the sample return mission. The spacecraft includes apparatus for collecting in-situ materials and one or more additive manufacturing devices which may be utilized to create sample return canisters, a heat shield, place in-situ materials in the canisters, and the like. These systems facilitate building ballistic reentry vehicles using In-Situ Resource Utilization (ISRU) located on the target celestial body in order to facilitate sample return missions. These resources may be fashioned into a heat shield and sample return canister using an organic binder produced from bacteria taken with the mission in order to form a composite ‘concrete’ with gathered regolith. The bacteria may replicate with sunlight and water derived from ice inside a bioreactor, forming the protein needed to create an organic binder for use with the captured regolith and thus creating a biocomposite material. Samples may then be placed inside the constructed containers and sealed with the same manufacturing process. Because the large heat shield and supporting structure on the reentry vehicle are created at the destination, more mass can be added to the initial spacecraft launched and much more mass can potentially be lifted from the surface of the target celestial body and returned.

In some aspects, such a regolith-binder extrusion printing process is less energy-demanding compared to sintering which requires a focused laser, electron beam, or microwave beam to fuse regolith particles together. Sintering of regolith by thermal means may require more than 0.5 MJ of energy for 2 kg of finished product. Melting of regolith may require even more energy. By contrast, the regolith biocomposite material disclosed above, which relies on biological production of the binding agent, may require only approximately 5 J of energy to produce 2 kg of finished product.

In lieu of an organic binder produced on site, the spacecraft may include an organic or inorganic binder supply. The binder may be combined with in-situ material in order to additively manufacture parts.

Referring now to FIG. 1, a flowchart depicting an exemplary process 100 for preparing in-situ materials for use as manufacturing feedstock, according to an aspect of the present disclosure, is shown.

All manufacturing processes require the base material (i.e., the feedstock) be prepared to certain shapes, sizes, and composition in order to be handled by machinery or humans and create the necessary end product. Most traditional manufacturing requires the workable material be larger than the final product that is to be machined. On the other hand, many additive manufacturing process require the feedstock to be small relative to the end product being produced, thereby requiring processing and sorting of the collected material. Some additive manufacturing devices require the feedstock be divisible on the micron scale and constrained to particular bulk diameters, depending on the device utilized. Processes requiring powder have limitations to the shape and size that can be put in the system for use. Homogeneity may also be a requirement for powder-based additive manufacturing devices as any nonconforming or contaminating material reduces the quality of the final product. Processes requiring wire feed material have limitations to the diameter of the usable feedstock. Some additive manufacturing processes does not require homogeneous material in order to produce functional parts. The processing effort required to be applied to collected in-situ materials depends on the manufacturing process that the collected material will ultimately be subjected to.

Process 100, at least a portion of which may be executed on a celestial body such as the Moon, Mars, an asteroid, or the like, facilitates production via additive manufacturing of parts, structures, or portions thereof from conditioned in-situ materials. Process 100 begins at step 102 with control immediately passing to step 104.

At step 104, in-situ materials are collected. The collection of materials can be performed by gathering surface material such as regolith, mining resources from subsurface veins, collection of resources that are free standing (e.g., manmade space debris, manmade debris, asteroids, or the like), or other processes apparent to those skilled in the relevant art(s) after reading the description herein.

At step 106, the collected material undergoes the first of one or more steps to prepare the material for utilization in manufacturing. The collected material is placed in a processing device, such as a recycling device, grinder, or other device, where the material is processed. In various aspects, depending on the desired materials for manufacturing, the local environment, and the composition and structure of the collected materials, the collected material is physically and/or chemically processed into a usable form. In an aspect, such chemical and physical processes are similar to Earth-based processes. In another aspect, recycling devices, grinders, casting processes, and other devices adapted for use in varying and/or non-one G environments are utilized. Similarly, such devices may be used at other steps of processed disclosed herein

At step 108, usable material is separated from contaminants. Such contaminants may be a by-product of portions of process 100, contaminants from the local environment, or portions of the collected material which cannot be used for manufacturing. Separation may happen through physical, chemical, or electromagnetic means (e.g., using robotic sorters, centrifuges, magnets, or the like).

At step 110, the material may be conditioned in order to be utilized in manufacturing. Some material deemed for manufacturing process such as direct regolith binding, sintering, and casting requires little processing and separation but requires particle size to be in a particular range. Conditioning material for this process can take place by mechanical means such as sifting through appropriate sized grates. Other manufacturing methods requiring specific sized and shaped material can be satisfied by grinding, cutting, pulverizing, and chemically reducing until the appropriate parameters are met. Satisfying traditional manufacturing methods will require forming into blocks, plates, rods or other 3D objects that are capable of being machined. This can take place by casting, forging, extrusion, cold heading, stamping, screw machining, or forming powders into desired geometries.

At step 112, the conditioned material is converted into an appropriate feedstock. In some aspects, this step is omitted. In another aspect, a wire-based feedstock is required and the conditioned material is extruded.

At step 114, the feedstock is stored for later utilization.

At step 116, a desired part, structure, or portion of a structure is produced. Once the materials are in feedstock form, manufacturing can take place in-situ. Multiple items can be created using various manufacturing techniques. Components could include sample containers, storage facilities large and small, transportation devices, mining facilities, shelters, solar power facilities, heat shields, radiation shields, debris shields, walkways, launch pads, and other structural elements such as trusses.

Process 100 then terminates at step 118.

Referring now to FIG. 2, a flowchart depicting an exemplary process 200 for construction utilizing in-situ materials, according to an aspect of the present disclosure, is shown.

Process 200, at least a portion of which may be executed on an asteroid, depicts an aspect of process 100 and facilitates production via additive manufacturing of parts, structures, or portions thereof from conditioned in-situ materials. Process 200 begins at step 202 with control immediately passing to step 204.

At step 204, in-situ materials are collected from the asteroid. In an aspect, minerals may be robotically mined from the asteroid and placed within a grinding apparatus or a recycling device for ultimate use by an additive manufacturing device positioned on the surface of the asteroid. In another aspect, the collected material is placed in a storage container for later conditioning, transportation to the conditioning device, or the like.

At step 206, the collected material is conditioned for utilization in manufacturing. In various aspects, the conditioning carried out is the conditioning described in relation to steps 106, 108 and/or 110.

At step 208, the conditioned material is converted to a feedstock for an additive manufacturing device.

At step 210, desired items are produced on site utilizing the feedstock created from the in-situ materials and process 200 then terminates at step 212.

Referring now to FIG. 3, an image of various configurations of parts created from in-situ materials, according to various aspects of the present disclosure, is shown.

In-situ materials may be utilized to produce a variety of objects. In various aspects, objects are created comprising in-situ materials mixed with binders, resins, or other agents provided from Earth or another location.

Objects which may be produced include sample return containers 302, ablative or non-ablative heat shielding 304, a part structure or frame 308, and the like. More generally, objects 310 having the desired structure, size and other features may be created such as blocks, spheres having an internal volume, columns having internal and/or external features and the like. A sample 306 of the celestial body where sample return container 302 is produced may be placed inside sample return container 302 via an additive manufacturing device (see FIG. 6) or another means. Sample return container 302 may have an internal volume 312 where sample 306 may be placed for return.

Referring now to FIGS. 4 & 10, an image of various structures created on a celestial body from in-situ materials, according to various aspects of the present disclosure, is shown.

In various aspects, apparatus, systems, and methods of the present disclosure may be utilized to produce infrastructure such as habitats 402 (labeled as habitats 402 a, b in FIG. 4), launch or landing pads 404, surfaces 406 (labeled as surfaces 406 a, b in FIG. 4), antenna support structure 1002, foundations 1004, pressure vessels, pipelines, burms, walls, bricks, scaffolding, or portions thereof. Surfaces 406 include roads, walkways, storage areas and the like. FIG. 10 depicts habitat on a celestial body such as the moon.

Referring now to FIG. 5, a flowchart depicting an exemplary process 500 for recovering a sample from a celestial body, according to an aspect of the present disclosure, is shown.

Process 500 facilitates a sample return mission wherein the sample return vehicle is not transported from the surface of the Earth (i.e., launched). Rather, the sample return vehicle is manufactured in-situ, enabling a larger sample return vehicle, a smaller launch spacecraft launched from Earth, and the like. In various aspects, additive manufacturing of sample return container 302 and/or sample return vehicles are facilitated in order to bring samples from celestial bodies to other locations in the solar system, including Earth return. This reduces launch mass from Earth as well as complexity for harvesting lunar samples and stowage for Earth return. By creating the sample return vehicle or a portion thereof via additive manufacturing and using the sample material as feedstock (i.e. regolith as feedstock), a sample return mission can be far more feasible.

Process 500, at least a portion of which may be executed on a celestial body such as the Moon, Mars, an asteroid, or the like, facilitates a sample return mission. Process 500 begins at step 502 with control immediately passing to step 504.

At step 504, a spacecraft comprising an additive manufacturing device, an in-situ material collection device, and material collection and conditioning devices lands on a target celestial body. The spacecraft is adapted to land on the celestial body, collect a sample of the celestial body, construct a sample return vehicle and launch the sample return vehicle (e.g., back to Earth).

At step 506, sample 304 is collected. In an aspect, sample 304 is collected utilizing the same methods for collecting materials to construct parts or structures via additive manufacturing (e.g., collection step 104, collection step 204). Sample 304 may be collected via other processes apparent to those skilled in the relevant art(s) after reading the description herein.

At step 508, a sample return vehicle is constructed utilizing in-situ materials. In an aspect, sample return container 302 is constructed and portions of a sample return vehicle are constructed utilizing process 100. Process 100 may utilize equipment contained in the sample return spacecraft.

At step 510, the assembled sample return vehicle is launched and process 500 then terminates at step 512.

Referring now to FIG. 6, a series of images depicting various stages of an exemplary process for recovering sample 304 from a celestial body, according to an aspect of the present disclosure, is shown.

Landing craft 600 is configured to gather sample 304 from a celestial body, place sample 304 in a particular location (e.g., on/in/as a portion of a sample return vehicle), and additively manufacture sample return container 302 around sample 304 in order for it to survive the journey back to Earth or another destination. A sample return vehicle 606 or sample return container may additionally comprise heat shield 306. This type of effort would be greatly beneficial to specifically the lunar environment where the regolith is widely available on the surface and capable of being used for manufacturing and the material holds the properties that would allow it to reenter the Earth's atmosphere if the production piece is designed properly. Through an ablative process, the additively manufacturing heat shield built using the in-situ resources will protect the sample inside from being destroyed during re-entry.

Landing craft 600 comprises an additive manufacturing device 602 comprising an extruder 612 positionable by an arm 610 (FIG. 6:1). Arm 610 may contain feed channels for feedstock utilized by extruder 612. As will be apparent to those skilled in the relevant art(s) after reading the description herein, feedstock may be supplied to extruder 612 via other pathways or mechanisms. Additive manufacturing device 602 may construct sample return container 302 (FIG. 6:3-4) and be used to place sample 304 (FIG. 6:2) within sample return container 302. In an aspect, sample 304 is placed by the extruder of additive manufacturing device 602 within a partially completed sample container 302 and container top 604 is subsequently manufactured and placed over sample 304. Container top 604 may also be heat shield 304. Upon completion of sample return vehicle 606, vehicle 606 may be launched on a return trajectory to a return location 614 such as Earth or another destination in the solar system (FIG. 6:5). Exhaust nozzle 608 may be additively manufactured from regolith or other in-situ materials, supplied with vehicle 606 or created by additive manufacturing device 602 using an on board supply of material. In an aspect, at least a portion of landing craft 600 remains behind on the celestial body (FIG. 6:6). In another aspect, the entire craft 600 is launched in order to return to Earth or another destination.

In an aspect, landing craft 600 may be launched in its entirety after collecting sample 304, leaving no portion of landing craft 600 behind.

In an aspect, additive manufacturing device 602 constructs sample return container 302 and attaches to the top of sample return vehicle 606. In this way, the sample return container is built one layer at a time using in-situ resources, such as a concrete-like composite. Sample return container 302 is built with an open volume which is filled with the sample 304. After sample 304 is added, additive manufacturing device 602 continues to build the sample return container 302 in such a way as to encapsulate sample 304 inside, creating a ballistic re-entry heat shield that is capable of allowing sample 304 to survive re-entry. Also, since the entire sample return container 302, with sample 304 inside, is attached to sample return vehicle 606, it will have a physical connection to re-entry avionics, power, communications, and entry, descent, landing capabilities. The additive manufactured aspect provides the needed heat shield for re-entry along with a method of returning the desired sample 304.

Referring now to FIGS. 7-9, perspective views of landing craft 600 configured to collect and process in-situ materials from a celestial body for use in additively manufacturing portions of sample return spacecraft 606, according to an aspect of the present disclosure, are shown. Spacecraft 606 b is partially completed.

Landing craft 606 may include a body 702 which houses processing systems, control electronics, communications equipment and includes two or more launch stands for multiple return spacecraft 606 (labelled as spacecraft 606 a & b in FIGS. 7-8). Landing gear 704; lander body 702; collector 706 may be mounted on arm 610. In some aspects, collector 706 and extruder 612 are mounted on the same arm joint 708. Collector 706 may be a scoop, claw, vacuum or other device for gathering material from the celestial body craft 600 lands on. Collector 706 may deposit raw collected material into a hopper 714 connected to conditioning systems housed within landing craft body 702. Conditioning systems process the received in-situ material into feedstock for additive manufacturing device 602. Body 702 may also house bioreactors, binder sources, and other systems for facilitating converting the in-situ material into feedstock. Power system 716, such as a radioisotope thermoelectric generator or battery pack may power landing craft 600 systems. In other aspects, craft 600 includes solar arrays. As shown in the cut away view of FIG. 9, heat shield 304 may contain sample 306 within a cavity created therein.
